Book excerpt: This study seeks to provide empirical evidence on the economic impacts that are generated through the Geographical Indication (GI) process beginning with the official recognition of a GI and the steps that follow. It focuses on the food sector and reviews nine cases, offering a variety of national contexts and local value chains. The approach, considers “operational” GI processes: those in which a code of practice (or specifications) is defined and the GI is used and managed by a collective organization. The synthetic outcome of these nine cases show the positive effect of GIs on the economy and confirm the importance of specification that is well defined and implemented through producers’ coordinated action.
